like modeling of the environments.

So this kind of transition and also this kind of data flow is really enabling factors of both getting the best of both physics and the geometry and consistency, as well as all the power and magics from the data and compute.

I also want to add to that.

So like there are, if you put things more specific, simulation can provide two levels of benefits.

The first one is reliability, and the second one is efficiency.

So for reliability, if you're thinking about a robotic system working reliable in the real environment, you need data to provide systematic coverage of all the state space and the variations that robots might encounter.

That's

how you can learn of how is that is robust.

So with simulation, you can do systematic randomizations and control and the variations of lighting, frictions, geometries, object types, and also all different kinds of physical parameters to making sure you have sufficient coverage of the state space.

So this is what can give the robotic systems reliability.

And second is about efficiency.

So right now, many people are doing teleoperation.

And if you look at many of the teleoperation device, imagining all the actual skeletons you are using, you are actually collecting the data at a speed that is actually slower than human actually doing the task.

But for many of our clients, human speed to them is not good enough.

They want faster than human speeds.

So for the robot to move faster, it's not as simple as just drive the robot faster because the gravity doesn't change.

But in simulation, you can do systematic speed up of the robot's behaviors to train the robots such that it considers all the dynamics, changes of the environment.

So this is what can give our clients, for them, efficiency.

So both for the reliability and efficiency, there are some kind of very unique values where simulation can provide.

There are essential, like two specific use cases, especially around both training and also around evaluations.
